SUSPENSION-JACK FOR REMOVING JOURNAL-BOXES OF CARS.

SPECIFICATION forming part of Letters Patent No. 298,298, dated May 6, 1884.

(No model.)

clear, and exact description of my invention,

which, with the aid of the accompanying drawings, will enable a skilled artisan to make and use the same.

I-Ieretofore the lifting-jacks for removing the bearings from the oil-boxes of cars have generally been supported on pedestals or stands set upon the cross-ties or upon bridg- In many situations such support was unreliable, if the road-bed was not solid or if i ing.

the tie was unsound. Besides, the hydraulic jacks and most of the screw and lever jacks were liable to ram in the bottoms of the oilboxes of heavy-laden cars. The time consumed in getting the jacks in right position was also the cause of detentions. My improved device therefore has its support independent of the ties or ground, it being suspended on the car-wheel whose bearing is to be removed, and it takes hold of the 0il-boX by embracing it by suitable means or connection to handle it safely, and with equal facility at any point along the road, and quickly.

The main objects of my invention are therefore to secure an unfailing support for the jack-purchase, a harmless hold on the oilboX, and connecting simple lever mechanism that may be quickly applied in ready condition at any moment, and unobstructive to access to the bearing which is to be removed. Its principal novel and useful features are, first, an arm transversely extended on the car-wheel, having hook to clutch the wheelflange and a notch or hold to apply on the summit of the tread of wheel; second, a hanger suspended on said arm for supporting the lifting-lever pivoted thereto; third, a swinging link pivoted to said lever. and to a cross-bar, to which latter is attached a chain for embracing the oil-box adjustably for obtaining the right lift for oil-boxes of different makes; fourth, the combination of said parts in such form as to be self-setting when the oil-box is raised as desired, and with removable lever-handle to be out of the way. I attain said objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents a transverse section of car-wheel, the oil-box, and car-axle with my suspension-jack in position ready for jacking up the oilbox and truck. Fig. 2 represents a similar view of the same with parts in position as when the oil-box has been duly elevated thereby and the jack self-set by swinging link over center or lever-fulcrum. Fig. 3 represents a cross-section of oil-box and bearing on axle and parts of my jack applied to said box.

Figs. 4C, 5, 6, and 7 represent, respectively, the

lever proper, the hanger-plates, the suspension-arm, and the swinging link.

Similar letters denote the identical partsin the several views. y

The suspension-arm A is preferably made of steel bar, of aboutone by three inehes'crosssection at middle, and is provided at its inner end with the hook A, adapted to clutch the flange A of a car-wheel, H. A little distance in from said end it has a shallow notch, N, adapted to hug the outer edge of said wheel and to perch on top of it. The outer end of said arm is extended a little higher than height of said wheel, and has pivoted or riveted thereto the hanger B in one or two parts. Said hanger is clevis form at lower end, and has fulcrumed therein the lifting-lever O by bolt or rivet a. Said lever O has a socket in it to freely admit in it the removable extension or handle D. Said lever O has its arm 0 shorter than the space L in said clevis, that it may be allowed to reverse in it, or cook and set over center, thus maintaining its elevated position automatically when the handle D is deflected, as shown in Fig. 2. Said short arm 0 is also vertically slotted, and the swinging link Z is pivoted or hinged therein at (I. Said link is joined at its other end to staple Q on cross-bar M; or it may be pivoted to the latter through lugs thereon. Said link Z is made retreating at its middle, that it may swing over the rivet or bolt a, to present its ends beyond the same, and thus by the stress upon said ends keep securely set while the bearing R is being removed. Said cross-bar M is provided near its ends with a screw-eye, O, and nut an, and a screw-hook, I, and nut n, and the chain F or its equivalent, which is adjusted by said nuts to adapt the length thereof to oilboxes of various sizes, and also to compensate for ear-wheels of various heights, and thus regulate the length of the li nk-connections with said lever-arm O, to attain the right elevation of the oil-box G at the end of the downstroke of the handle D for removal of said bearing R. The chain F is applied to the oilboX G nearly vertically beneath the outer end of arm A, and in such manner that said oilboX may lift squarely or balanced, and not slip on the chain or cock on it. WVhen the oil-box is fully elevated by my device, the handle D is removed from its socket in O, and the door J may then be opened and unobstructed entrance had to the interior of said box to lift the bearing R from'its seat and move it outward over the collar on the end of journal 0. The suspension arm A is nearly vertically above the center of car-wheel and in line with the axis thereof. Therefore weight of truck suspended by the leverage 011 said arm will that hinged bars may be substituted for the chain F, but that neither of said changes is ad I vantageous.

solely to raise car-trucks.

ed at its inner end with a hook for clutching 5 the flange of a car-wheel, and adjacent thereto a hold for hugging the outer edge of the tread of said wheel, substantially as and for the purposes set forth.

2. A lifting jack having for its support an extended arm, A, provided at its inner end with hook A and hold N, for attaching it instantly on a car-wheel, and provided at its outer end with hanger B, in combination with lever G, coupled with swinging link Z, all pivoted or hinged together, and operating to set automatically said lever when the swinging link is raised full throw, substantially as herein shown and described.

3. The combination, with the suspending parts A and B and the lifting parts 0 and Z, of means F M Q for hitching the jack mechanism to an oil-box, G, or other object vertically beneath the pointB of suspension on said part A, and operating substantially as set forth.

4. The combination,with the suspension-arm A, hanger B, lever 0, provided with removable handle D, and swinging link Z, constitut ing a lifting-jack of invariable throw, of the adjustable hitching device consisting of crossbar M, with coupling-staple Q thereon, and a chain, F, connected with said cross-bar by screw-eye O and screw-hook I and nuts mn,

to vary the length of the hitch, substantially as and for the purposes set forth.
